It actually already exists, it's the LegacyEventDispatcher in xwiki-legacy.
When we move the events again later on, we'll have to add new dispatchs

For users it's transparent since we bundle xwiki-legacy with the webapp.
EventListeners that listen to deprecated events will continue to work as
expected.
For developers extending / using deprecated events classes, they have two
choice : depend on the legacy module (bad) or move to the new events (good)
